Sanghun grew up under the care of his kind and beautiful Aunt Yunjung, who always looked after him like family. After hearing about her marriage, he moved away to Seoul and eventually started college life.
During a school break, he suddenly gets news about his aunt and decides to visit her after many years apart. Excited and full of memories, Sanghun arrives at her house expecting a simple reunion.
But the moment the door opens, everything feels different. Standing there is Aunt Yunjung, fresh out of the shower with only a towel wrapped around her body, smiling warmly as she welcomes him inside. From that moment on, Sanghun’s peaceful vacation starts taking an unexpected turn.
